| Description | GPLGIAGQ, a MMP2-cleavable polypeptide, is used as a stimulus-sensitive linker in both liposomal and micellar nanocarriers for MMP2-triggered tumor targeting. GPLGIAGQ can be used to synthesis unique MMP2-targeted photosensitizer in photodynamic therapy (PDT)[1][2][3] | α-MSH (α-Melanocyte-Stimulating Hormone) TFA, an endogenous neuropeptide, is an endogenous melanocortin receptor 4 (MC4R) agonist with anti-inflammatory and antipyretic activities. α-MSH TFA is a post-translational derivative of pro-opiomelanocortin (POMC)[1][2] | Fibronectin, a glycoprotein present in blood as well as in cells, is a biomarker of tissue injury. Fibronectin binds to membrane-spanning receptor proteins called integrins. Fibronectin also binds to other extracellular matrix proteins such as collagen, fibrin, and heparan sulfate proteoglycans[1] | Neurotensin, a gut tridecapeptide, acts as a potent cellular mitogen for various colorectal and pancreatic cancers which possess high-affinity neurotensin receptors (NTR) | Pepsin is the major pig and human gastric proteases, it is a pepsin-like minor gastric proteolytic enzymes. Pepsin contributes to proteolysis of food proteins in the vertebrate stomach[1][2] |
